Set up high availability data to Amazon Managed Service for Prometheus using the Prometheus Operator Helm chart

To set up a high availability configuration with the Prometheus Operator in Helm, you must apply external labels on all instances of a high availability group, so Amazon Managed Service for Prometheus can identify them. You also must set the attributes replicaExternalLabelName and externalLabels on the Prometheus Operator Helm chart.

Example: YAML header

In the following YAML header, cluster is added to externalLabel to identify a Prometheus instance agent as part of a high-availability group, and replicaExternalLabels identifies each replica in the group.

replicaExternalLabelName: __replica__
externalLabels:
cluster: prom-dev
Note

Certain versions of Kubernetes (1.28 and 1.29) may emit their own metric with a cluster label. This can cause issues with Amazon Managed Service for Prometheus deduplication. See the High availability FAQ for more information.
